Zuckoff

Can anyone tell me how the word Zuckoff relates to my motorhome? Is it a type of chassis?
I am trying to use a Peugeot disc based workshop manual and there are so many varieties of body chassis type variations mentioned.
I know it has disc brakes at the rear which helps and that the 3 litre engine (157BHP) does not have a cam belt but two chains( big relief) so I am trying to fill the gaps in my knowledge of the vehicle.
Oh it is a 2008 early Autocruise ( pre Swift takeover) Gleneagle

I rang 6 motorhome dealers, two motorhome manufacturers and emailed Peugeot Business re this subject ( that's how sad I am to find out the answer to the question)
Guess what .....none of them know and my query to Peugeot just bounced back. I cannot understand when motor homes are advertised as 440 (or 355) Zuckoff ( and on my logbook) that nobody seems to know what it means.
I looked at the aluminium plates under the bonnet and one is for the cab and the other labelled Alko is for the chassis. I also saw that the VIN numbers on each were slightly different which was a surprise!
You learn something useless every day.
The quest to find Mr Zuckoff continues, I have asked Interpol and the CIA for help......or should I just give up??? The problem with retirement is that time is not an issue.

I have just emailed the dealer I bought it from as there is a one letter difference between the VIN showing through the windscreen and the plates under the bonnet above the radiator. The two plates, Peugeot and Alko have the same details but the windscreen one shows MAA and the under bonnet ones show MAB. Any ideas?.
Mr Zuckoff is on hold for now

OK here are the two different VIN numbers and I have either found them invalid on an on line check or for a 2001 model, there is something wrong here. Waiting for the respected caravan and motorhome dealer to get back to me.

This is really weird. The numbers at the end work fine in a Peugeot workshop manual and come up with the 3 litre engine information. It seems that both numbers on the vehicle( well the letters anyway) are incorrect but also one letter different from each other . The vin on the original Peugeot service record is the same as one of the numbers on the vehicle so that looks genuine. I do not yet have the registration document as there was a private plate on it and the dealer has changed it for me back to the original number . I am just waiting for it to arrive. There were two previous owners one lives locally and the vehicle has been looked after by the local dealer I bought it from . The last owners bought it from Marquis in Preston a well knwn dealer and I have the receipt for their purchase .
It all looks genuine apart from the Vin anomaly . How could it get to five years old and nobody noticed? It even has a fresh MOT locally. I won't sleep until I find out what is going on. Thanks for your help, I will report back here when it is sorted. Needless to say Mr Zuckoff is now on the back burner!
